Dr. Athos D. Moretti (1907-1993) was the director of a major Swiss pharmaceutical company who initially collected paintings. In the 1950s, at the urging of his wife, he switched to coins, and in time built up significant collections of Greek silver, Roman gold and Milanese coins of all eras. A generous patron of art and scholarship, he made his collections widely available for study and financed the publication of several important references. His gold collection was bought en bloc by Numismatic Fine Arts and sold anonymously at auction between 1989 and 1991. Very discrete during his lifetime, Moretti possessed a keen eye for quality and his collection pedigree has become highly prized since his passing.
